MPAA sues P2P movie sharing users

The Motion Picture Association of America (MPAA) is suing an undisclosed number of people who they claim are sharing movies online. This follows the same heavy-handed approach by the RIAA against music downloaders.

I am not sure what the economic argument is. DVD sales and rentals are more than robust, and movie attendance figures have not suffered whatsoever. Seems like yet another attempt to cover the sun with one finger.
